Hello. I wanna ask how come Power Converters and Ultrasonic drivers became an application for LM386. How do I use LM386 in those applications? What is power converters?What does it do? What is an Ultrasonic drivers? What does it do?

Sorry about that. Well I don't know about power converters and ultrasonic drivers and our professor is telling us to use LM386 in power converter and ultrasonic driver.So how do I use LM386 in power converter and in ultrasonic driver?

The Texas Instruments' LM386 datasheet lists those applications. The bandwidth with pins 1 and 8 open is 300kHz so it could be used in those applications although it is described as an audio amplifier.

Did your professor give you any specifics ?
If so, please post that info.

Normally, devices that generate signals (op Amps, logic chips, crystal oscillator circuits), do not have enough power to do anything more than generate signals. Therefore, you need to connect these signal generating devices to a "driver". A driver is a circuit that can amplify the input signal to provide sufficient power to any motor, loudspeaker, ultrasonic horn or other device that can really make something happen.

Although the LM386 is referred to as an "audio amplifier", it can amplify any signal in the audio frequencies (and even above) for non-audio applications. Audio frequencies are generally from 20 Hz to about 20k Hz. The LM386 will be useful from DC to 30k Hz (10x amplification) to 100kHz (3x amplification).

He didn't give any specifics rather he just told us to research about the significance of active filter into the power converter and in ultrasonic drivers. He just told us that ultrasonic drivers has something to do with pressure.

Thanks for that explanation. I already tried doing that. I used LM386 as an audio amplifier and it really works when I tried in Multisim. But my problem now is what does it do in Power Converters and in Ultrasonic Drivers?
